3.  19 In an experiment, thrombus formation is studied in
areas of vascular damage. After a thrombus forms in an
area of vascular injury, the propagation of the thrombus
to normal arteries is prevented. Researchers identify a
substance that diminishes thrombus propagation by
binding to thrombin, converting it from a procoagulant to
an anticoagulant that activates protein C. Which of the
following substances is most likely to produce this effect?
 □ (A) Calcium
 □ (B) Fibrin
 □ (C) Platelet factor 4
 □ (D) Prothrombin
 □ (E) Thrombomodulin
 □ (F) Tumor necrosis factor

8.  24 A 78-year-old woman falls in the bathtub and
strikes the back of her head. Over the next 24
hours, she becomes increasingly somnolent. A
head CT scan shows an accumulation of fluid
beneath the dura, compressing the left cerebral
hemisphere. Which of the following terms best
describes this collection of fluid?
 □ (A) Hematoma
 □ (B) Purpura
 □ (C) Congestion
 □ (D) Petechia
 □ (E) Ecchymosis

12. □ (F) Thromboxane

16.  32 A 23-year-old woman with an uncomplicated
pregnancy develops sudden dyspnea with cyanosis and
hypotension during routine vaginal delivery of a term
infant. She has a generalized seizure and becomes
comatose. Her condition does not improve over the next
2 days. Which of the following findings is most likely to
be present in the peripheral pulmonary arteries?
 □ (A) Aggregates of red blood cells
 □ (B) Amniotic fluid
 □ (C) Fat globules
 □ (D) Gas bubbles
 □ (E) Thromboemboli
